Hi,

Voice output serial port is enabled on some Huawei models (e.g. E169) without
problems, but for example on E173u-2 it is never enabled during an incoming
call. There might also be other Huawei models having the same issue.

I traced the issue down to "^DDSETEX" AT command, which is used to notify
the device to start streaming audio. It seems that Ofono sends this
command too early on incoming calls. The command should always be sent
*after* the dial "D" or answer "A" command. The patch fixes this behavior
and afterwards voice will also work on E173u-2.

Best regards,
Jarkko
